Description

Sinopec L-QB300 Thermal Conduction Oil is formulated using a narrow-cut, highly refined mineral oil, which has excellent inherent thermal and oxidation stability, together with selected detergent, dispersant and antioxidant additives. It is recommended for use as a heat transfer oil in closed, forced or unforced, circulation systems where the bulk oil temperature does not exceed 290°C or 600°F. 

Features & Benefits

Sinopec L-QB 300 Heat Transfer Oil is suitable for use in:

  • Closed heat transmission systems with forced or unforced circulation operating at a maximum bulk temperature of 290°C.
  • Drying and heating process, such as those used in timber processing, textile finishing, food processing and the chemical industry.

Features & Benefits

  • The narrow-cut base oil has a high distillation point, which avoids pressure build up in the closed circulation system.
  • Excellent thermal and oxidation stability ensure the oil does not crack, break down or produce deposits at high temperatures, extends the life of the oil, protects the system and reduces maintenance costs.
  • The high flash point and low evaporation rate enable the oil to be used in closed systems up to 290°C.
  • Good fluidity at low temperatures ensures good oil circulation, even at low-temperature start-up.
  • The high specific heat and thermal conductivity of the oil enable rapid heat transfer, improved operating efficiency and lower operating costs.
  • Good rust and corrosion resistance protect the system and reduce maintenance costs.
  • Used paraffinic mineral oil can be recycled or disposed of more easily than naphthenic or synthetic fluids.

Good value for the money.
Size: 9.5 Wide, Color: Beige
Comfortable right out of the box. Great style and well made. The more you wear the softer they get but maintain their overall appearance.

Comfortable fit for slip-in fabric shoes
Size: 14, Color: Black/Black
My first experience with Marc Joseph. I typically purchase dress and casual work shoes from Florsheim and occasionally Rockport. I'm giving these four stars because the initial fit and feel appear solid. Depending on the shoe brand I wear a size 14 or 15. My feet are slightly wide but I don't alway need wide fit. These size 14 fit well with wide enough toe box. I've tried slip in shoes before and they just don't feel right. These somehow work and there is no heel slip. My only reservation is the high lip on the heel for slip-in and hope they dont catch pant hems. I gave 4 stars because I'll have to determine durability. Granted they are a light fabric shoe with a soft rubber tread. I'd like them to last for at least 6 months..and use them for business casual work wear during warm weather.
